TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 287,403, dated October30, 1883.

I Application filed October 9, 1882. (No model.) I

To all whom it may concern:

Be it known that I, HENRY R. AUSTIN, of Norwood, in the county of St.Lawrence and State of New York, have invented certain new and usefulImprovements in Turbine WVater- WVheels; and I do'hereby declare thatthe fol-' lowing is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

'My improvements relate to turbine wheels having a conical hub risingabove the rim and buckets of thewheel; and theyconsist, chiefly, in twospiral grooves inthe cone, for the purpose of directing the water in twocurrents upon the buckets, and thus giving the water a spiral motionbefore the same strikes the buckets; and, also, my improvements coverother features, which will be understood by the following description.-

In the accompanying drawings, Figure 1 is a plan View of my improvedwater-wheel. Fig. 2 is a side view, showing the box or casing insection.

In the drawings, Arepresents my improved I wheel, having two buckets, B,overlapping each other about four inches. The shaftrests on the ordinarystep, M, and has a conical hub, F, attached thereto. This hub risesabove the rim A of the wheel, and has spiral grooves G- The wheel is tobe placed in a box or casing, I, having a spout, K, provided with agate, L. From this spout the water enters the casing above the rim A ofthe wheel, andon 5 aline of'a tangent thereof, or between the conicalhub and the casing, the hub diverting the flow outward from the centerto the circumference, thus increasing the power or force of the water;also, the spout is steeply inclined downward, in order to increase thestroke or momentum of water upon the wheel or bucket. The grooves G, ina full-sized wheel, are several inches in depth, and they direct thewater upon the highest parts of the buckets B, thus adding power to thewheel. The dischargeopenings from the buckets B are diminished insize,when desired, by means of a wedge-shaped block, D, which is maderemovable and fitted to the side of the hub. By this means the speed ofthe wheel and the use of water are diminished when desired.

Having thus described myinvention,what I claim is- 1. The describedturbine wheel, having the ing buckets B and conical hub F, the removable block D, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

I HENRY R. AUSTIN.
